SIGN ALL-ALARM SYSTEM.

Specification of Letters Patent.

Patented Jan. 7, 1908.

Application filed April 30, 1906. Serial No. 314.455.

To allwhom it may concern:

Be it known that I, OLIVER B. Kirstin, a c'itizenof the United States, residing at Norwood, in the (.ounty of Hamilton and State of Ohio, have invented. certain new and use is to provide means whereby theapparatus.

T is set in motion some time prior to the operation of the signal transmitting means.

Another object of my invention is to pro- V de means whereby the apparatus 18 operatcd automatically t'o transmit a signal from Q a transmitter point to a central oflice, in

which after the apparatus has been set in motion, 1t is positively operated by power and continues in such positive operation ior a limit of time before the transmitting wheel is positivelybrought into operation.

The features of the invention are more fully set forth in the description of the accompanying drawings, forming a part of this specification, in which:

Figure 1 is a diagrammatic view of the I alarm system, illustrating the transmitting point and the receiving point. Fig. 2 is a side elevation of the signal indicating mechanism, and its electrically controlled operating mechanism.

The function of this invention relates principally to operating a signal system to be used in conjunction with a sprinkler system installed in a building, in which the apparatus is operated automatically by the opening of a sprinkler head, such sprinkler head being opened by fire or otherwise, and in which instance it is desirable to notify a central office that such sprinkler head or heads have opened, in which instance said central oliice can notify thefire department or salvage corps of the same, to prevent further damage to the contents in or to a building.

The apparatus is in electrical circuit with circuit controlling devices applied to the main or distributing pipe of the sprinkler system, and the apparatus in this pipe system is of such'construction as to effect a pressures in the water mains that a water hammer effect is produced in the sprinkler mains, which would cause the circuit to be broken and the signal mechanism to be operated, but which water hammer effect is but momentary and therefore the signal apparatus must be provided with retarding means, whereby the signal is not transmitted to the central office for a period of time, say, twenty seconds, that is, water must be flowing through the sprinkler system twenty,

seconds before a signal is transmitted to. the central oflice. The instrumentalities employed' for accomplishing thisv result, are as follows :1 represents the water main of the sprinkler system at a point to which make and break mechanism is connected controlling the circuit of the signal apparatus. One end of sai d main is extended to the distributing mains of a city water plant or the like, the opposite end is extend d to the sprinkler system.

2 represents a valve hinged Within the pipe 1 and adapted when the sprinkler system is in normal position to close the passage in said pipe 1.

3 represents a sleeve leading into thepipe 1 below the valve 2.

4 represents a diaphragm fixed to the sleeve 3 by the sleeve 5. 6 represents a rod passing through said diaphragm 4 and fixed thereto, one end projecting upward and adapted to contact with the valve 2 when the same is in normal position. 7 represents a switch member fixed to said rod 6 for closing the circuit to the signal mechanism, hereinafter to be described. This rod 6 through the particular construction of mounting has a vertical pivotal action, and as the valve 2 is down in its normal position, it will depress the rod 6 within the pipe 1 and raise the outside end theLcof, and as the valve 2 rises the rod 6 will pivot-ally move to the position shown in the drawing.

Srepresents a shalt, one end oi which is squared and which squared end passes through a gear 9 journaled in the bearing 10. Said shaft 8 is adapted to slidably move through said gear 9 while the gear 9 is rotated, likewise imparting motion to the shaft 8.

11 represents a bearing for supporting the opposite end of shalt S.

12 represents a gear wheel fixed to the shaft of the motor 13 an electric motor, but it is obvious that a spring motor or other suitable power means can be employed adapted. to transmit motion. to the shaft- 8,

21 represents a spring for applying tension to the armature lever 19.

Thus it will be seen that when the shaft 8 is being rotated and the nut 20 is in engagement with the worm 14', it will cause the shaft 8 to be fed laterally while the said shaft is in motion toward the break wheel 17.- the magnet coils l8 shoulrl becomeenergizerl the will attract lever it) disengaging the nut 20 rom the worm 22 represents a collar fixed to the shaft 8, and 23 represents a coil spring encircling the shaft 8, adaptecl to move the shaft 8 into its normalposition when the nut is disengaged from the worm 14. 24, represents magnet coils. 25, represents an armature lever adapted to be attracted by said magnet coils 2 1 and 26 representsa coil spring' for apply ing tension to the armature lever 25. represents a switch contact fixed to and moving with said armatuge 2:3 and insulated therefrom, adapted to contact with the switch contacts 28, 29.

30, 31, represents switch to be closed by the switch member 7 gize magnet coils 18 and 24-.

32 represents a battery or source of electric supply. I

33 represents a wire leading from the source of supply 32 to the switch contact- 34 represents a wire loading from the switch contact 30 to the magnet coil 18.

38 represents a wire leading from the opposite pole of the motor to the switch. contact 29',

39 represents a wire leading from the. 28 to the source of electric supply 32, through wire 33.

Tnus when the apparatus is in normal position; switch member 7 will be in contact with the switch contacts 30, 31, closing the circuit to themagnet coils 18 and 24, through the contacts adapted to eherv nut 20 upon tuclinal ieeol imparted scares in this instance being following circuits i-l rom the source oi electric supply 32, through wire 33, switch contact F51, switch member *2, switch contact 3%, thence through wire t e magnet co s 18, through s I thence thr h wire 35 to tile or .24, thence th. high the magnet col 5 and wire 36 to the c oosite pole of the source of elec- As soon the switch merntheswitch contacts by of the valve 2 moving a, the magnet coils l8 and r become n iced, releasing theirarmature levers i9 ans. A5 respectively, permitting the armature lever 19 to beco i e engaged with the worm 14 and bringing the. switch member 27 of armature lever 25 into contact with the switch contacts 28. 29, closing the circuit to the electric motor 13ior revolving alt S, the circuit being as follows From the source of electric supply through wire 33 and 39, through switch meinber 27 thence through wire 38 to one pole oil the motor, through the wire 37 and wire 36 to the opposite pole oil the source of'electric supply, which potential will cause the shaft 8 to be rotated and move longitudinally through the engagement of nut 20 with worm i i. When the shaft 8 has been moved permit the clutch member 1-5 the clutch m ber 16 of the break wheel l7 he nut 2t? will then have traversedv to a position whereby it will become riisengagerl or ride off of the worm i4. descend further and bear against the shoulder 41% holding the clutch members 15, 16, into engagement with each other and stop the-longitudinal feed of shaft 8. But as soon as the magnet coils become energized attracting their respective armature levers the nut 20 will become (lisengaged from the shoulder 40, thereby permitting shaft 8 to be moved automatically into its normal position through the tension v 01" spring.23. This same automatic movement to normal position or the shai t 8 taking place irrespective oi any distance of the longithereto as soon as the same is released by the nut 20, caused through the energizing of magnet coils 18. Thus it will be seen that if thevalve 2 shall be caused toswin u ward breakin the circuit to the magnet coils 18 and 14, that the shaft 8 will immediately begin to rotate and be fed. forward, but that a signal will not be transmitted until the valve 2 has remained in its upward position for time to permit the clutch members 15 and 16 to become engaged. The longitudinal local or shaft 8 can bel tirned by adjusting the collar ii. on shaft 8, nioving' the shalt to the right a given period oi or left which will adjust the clutch members l5 anrl 16 to or from each other as desirei The signal is transmitted to the cen al o'flice as follows :-l he break wheel 17 is provided with a sleeve journaling in the single bearings 42. 43, 44, represent brush conbattery or source of electric supply.
